Image samples of 18F and 68Ga-filled NEMA NU 4-2008 phantoms performed for C-SC− and OC-SC+ acquisitions and reconstructed using the PSF algorithm with 20 iterations and 5 subsets. Axial slices are centred in the three different parts of the phantom: air and water inserts (left), uniform region (middle) and capillaries (right). The image window was normalized on the background of the phantom
